Title: Synchronizing circuit
IPC: H03K3/037
Filed: 1988-10-10
Abstract: A synchronizing circuit using a D-type flip-flop 1 for 
synchronizing an asynchronous input signal (ø₀) with a 
clock pulse can be in a metastable or logically undeter­
mined state when the transition of the state of the 
input signal coincides with the rise of the clock pulse. 
For preventing such metastability the synchronizing cir­
cuit comprises means to prevent the supply of the input 
signal to the flip-flop during the state of transition 
of the clock signal. These means preferably include 
gate means (10,12) for supplying the input signal and 
the complementary thereof as set and reset signals, 
respectively, to a Set-Reset-Flip-Flop 8, whose output 
is supplied to the flip-flop 1 as the input signal, 
said gate means (10,12) being controlled by a control 
signal obtained by delaying the clock pulse.

dose, an electrode structure (4) sealed to each end of the arc 
tube, and an insert member (11; 23, 24) positioned between the 
arc tube wall and at least one said electrode structure(4). 
The insert member (11; 23, 24) is arranged to define a wick 
(12, 13, 15; 22, 22′; 25, 25′) which is effective, in 
operation of the lamp, to more liquid dose, by capillary action, 
from a relatively cold region (R₁) of the arc tube (1) 
adjacent to said end into a reservoir (R₂) in a relatively hot 
region of the arc tube (1), and to further define a passageway 
(16) allowing movement of dose, by vapour diffusion, to said 
relatively cold region (R₁). The wick (12, 13, 15; 22, 22′; 
25, 25′) is so configured as to accommodate a variable volume of 
liquid dose. The passageway is configured to enable attainment 
of a desired operating pressure in the arc tube (1). The 
distributions of vapour pressure and temperature along the 
passageway encourage condensation of vapour at said relatively 
cold region (R₁) such that the wick (12, 13, 15; 22, 22′; 
25, 25′) can maintain a substantially continuous supply of 
liquid dose at the reservoir (R₂). Such a discharge arc lamp 
has an effective cool spot temperature, at the exposed surface 
of liquid in the reservoir (R₂) supplied by the wick (12, 13, 
15; 22, 22′; 25, 25′), which is higher than the temperature at 
the ends of the arc tube (1).

Title: Capillary device
IPC: G01N27/447
Filed: 1989-08-17
Abstract: A cross or T-shaped device (10) for use in capillary 
electrophoresis or capillary chromatography. The device 
includes a first capillary tube (12, 14) and a second 
capillary tube (16) connected to the first tube at a 
point between the two ends of the first tube so that the 
contents flowing in the second tube will mix with a 
fluid flowing in the first tube. The two tubes enclose 
spaces with cross-sectional dimensions less than about 
200 microns. The two tubes are connected so that there 
is substantially no dead space at the connection (20). 
The device is made by boring a hole at a selected 
location in the first tube, introducing an elongate 
guide member (50) into the hole, threading the member 
into the second tube until the second tube contacts the 
first tube. The second tube is then permanently 
connected to the first tube and the guide member is then 
removed to form a T-shaped device. To form the 
cross-shaped device, a second hole is drilled at a 
location opposite to the first hole and a guide member 
is introduced into the second hole as well. A third 
tube (18) is threaded onto the guide member on the 
opposite side of the second tube until it contacts the 
 
 
first tube. The third tube is also permanently 
connected to the first tube and the guide member is 
removed to yield a device with a cross-shaped 
configuration.

Patent EP-0385035-A3 (EP)
IPC: G01N21/03
Filed: 1989-12-12
Abstract: A crystallographic observation apparatus for the observation of 
behavior of crystals under pressure and for the measurement of the 
crystallization pressure and pressure of fusion of substances. The 
apparatus comprises a pressure chamber having a cavity and provided with 
a transparent observation window or windows, a pressurizing device for 
pressurizing the cavity of the pressure vessel, and small, entirely or 
partly transparent, entirely or partly elastic sample containing means 
for containing a sample, provided within the cavity of the pressure 
vessel. The sample can easily be changed for another sample simply by 
changing the sample containing means containing the former sample for 
another sample containing means containing the latter sample, or the 
apparatus can easily be cleaned after the completion of observation of a 
sample for the observation of the next sample, simply by washing the 
sample containing means. Since the sample is contained in the small 
sample containing means instead of filling up the cavity of the pressure 
vessel and the associated piping, the apparatus requires only a small 
amount of sample for observation. Direct observation of the behavior of 
the sample under varying pressure visually, a microscope or a combina­
tion of image pickup means and display means enables the accurate 
measurement of the crystallization pressure and pressure of fusion of 
the sample.

Title: Apparatus for monitoring the focus condition of a writing beam
IPC: G11B7/0045
Filed: 1983-08-04
Abstract: The present invention relates to a method and means for monitoring the focussing condition of the writing light beam impinging the writing surface of a recording medium. Systems for monitoring the focus condition of a light beam used in reproducing prerecorded information from a videodisc by a videodisc player operate by splitting off reflected light from the incident light beam path in a region where the incident beam is diverging. In this manner, the reflected beam entering the polarizing cube, placed in the diverging portion of the incident beam, produces a converging light beam diverted to the photodetector. Because of numerous problems in attempting to apply player concepts to writing machine, it has been common practice in the prior art of recording laser discs to periodically determine optimum focussing position for the various optical elements affecting focus by producing a series of test discs and playing back each disc or portion thereof corresponding to a particular combination of settings for the various optical parameters such as power and focus involved. The empirically derived conditions necessary to produce acceptable focussing conditions, however, are extremely costly due to the labor time involved in setting up and determining the optimum focus conditions as well as in the loss of videodisc production due to down time of the mastering machine. The present invention operates on the recognition of the fact that, although for all practical purposes a light beam from a laser device is collimated, it, in fact, is very slightly divergent as it emerges from the laser resulting from diffraction of the Gaussian intensity profile plane wave that exists between the laser resonator mirrors at the beam waist and from refraction as the output light traverses the thickness of the output mirror. Accordingly, since the beam exiting the laser tube is slightly divergent, the reflected light from the videodisc, even though a small in intensity, is conversely (provided the system is in focus) convergent as it passes in reverse direction through the diverging lens and on toward the output of the laser device and beyond to the conjugate point where it forms a real image of the source plane wave, thus eliminating the need for a relay lens. The present invention makes use of this slight divergence and convergence of the incident and reflected beams, respectively, at the exit end of the modulator to effect monitoring of the focus condition of the writing beam.
